OF NEW HAVEN, CONNECTICUT, ASSIGNOE TO THE PERCUSSION-FUSE FOR PROJECTILES.

SPECIFICATION forming part of Letters Application filed March 30, 1585.

To all whom it may concern:

Be it known that I, THOMAS G. BENNETT,

of New Haven, in the county of New Haven and State of Connecticut, have invented a new Improvement in Percussion-Fuses for Projectiles; and I do hereby declare the following, when taken in connection with accompanying drawings, and the letters of reference marked thereon, to be a full, clear, and exact descriptionof the same, and which said drawings constitute part of this specification, and represent, in-, Figure 1, a side view; Fig. 2, a head end view; Fig. 3, a longitudinal or vertical central section; Fig. 4, a transverse section; Fig. 5, a top view of the elastic sleeve; Fig. 6, a side view of the sleeve.

This invention relates to the fuse or percussion attachment constructed to be applied to explosive projectiles, and whereby as the projectile strikes, thereby suddenly reducing the velocity, a movable hammer will strike the primer and produce explosion, the object being a simple device, complete in itself, and which may be produced as an article of manufacture, for attachment to the projectile, and one in which accidental explosion in transportation or otherwise is prevented; andthe invention consists in acasing constructed to be applied through an aperture in the proj ectile one end of said casing provided with a primer-seat adapted to securely hold the primer, but; with an aperture through the seat, through which the spark from the primer will enter the projectile, and a hammer held suspended within the casing from possible contact with the primer, except in sudden interruption in the flight of the projectile, and as more fully hereinafter described, and particularly recited in the claim.

A is the casing, closed at one end by ahead, 13, from which an annular flange, a, extends,

a projection, C, to which a wrench or other instrument may be applied for screwing the easing into the projectile. The outer surface of the casing, beneath the head, is provided with a screw-thread, b, to fit a corresponding female thread made in the projectile.

opposite is introduced and fixed, preferably by a screwthread, as shown. The anvil is constructed with a seat, 6, upon which the primer F is laid. This seat opens upward, and is internally screw-threaded, and so primer has been placed upon its seat a corresponding screw-threaded ring, h, is introduced to bear upon the primer, and so as to hold it firmly upon its seat, the opening through the ring being in a central or concentric position.

Through the anvil below the primer-seat one or more apertures, i, are made, through which the fire from the primer may enter the projectile. Within the casing the hammer D is arranged. As here represented, the hammer is constructed with a vertical central recess, 1, corresponding to avertical central spindle, m, formed on or made a part of the head of the casing, the said spindle on serving as a guide upon' which and down. The hammer terminates in a nose, 12, adapted to pass through the ring h, and so as to strike the primer. Around the hammer a split elastic sleeve, E, is applied. This sleeve is constructed as seen It is of nearly-cylindrical form, open at one side, its internal diameter somewhat larger than that of the body of the hammer. Near the upper end it is constructed to embrace the body to prevent accidental movement one upon the other. This is best done by making in opposite sides of the sleeve one or more depressions, r,which form corresponding ribs on the inner surface of the sleeve, ribs will bear directly upon hammer. The sleeve extends down and so that its lower end may come to a bearing at the anvil before the nose of the hammer shall strike the primer, and

While I prefer to form the sleeve with the longitudinal or vertical rib s in one side, and

a corresponding the other, this rib may indicated in broken lines, Fig. 5.

The spindle m may be omitted; but I prefer I have represented the elastic sleeve as beserve as a stop to hold the hammer from accidental contact With I am aware that hammers have been susfuse-case by hammer, such a support for the hammer.
